What controls how much light enters the pupil?
The iris controls how much light enters the pupil by adjusting its size. In bright conditions, the iris contracts to make the pupil smaller, reducing the amount of light that enters the eye. In dim conditions, the iris relaxes to dilate the pupil and allow more light in for better visibility.

Which part of the eye is adjustable in accordance with the light conditions?
The iris is the part of the eye that adjusts in response to light conditions. It controls the size of the pupil, which determines how much light enters the eye. In bright light, the iris contracts to make the pupil smaller, and in dim light, it dilates to make the pupil larger.
How does eye control light?
The eye controls the amount of light entering by adjusting the size of the pupil. In bright light, the pupil contracts to let in less light, while in dim light, the pupil dilates to allow more light to enter. The iris, which contains the pupil, is the muscle responsible for regulating the size of the pupil.

What is aids to the human eye?
We only see things when light reflects from an object and enters our eyes. The human eye is only sensitive to certain types of light - we cannot see ultra violet light or infra red radiation. The human eye consists of 7 main parts: Lens: Focuses the light on the back of the retina by concentrating the light Retina: Sends messages to the brain to tell you what you are seeing - converts light into vision Pupil: Controls how much light enters the eye Cornea: - Protects the eye. - Controls and focuses incoming light Iris: (The colored part of the eye) Contracts and expands to regulate the amount of light that enters the eye. Optic Fiber: Carries electrical impulses (converted rays) from the eye to the brain. Conjunctiva: Its cell produces mucous with helps lubricate the eye. All types of eyes work in the same basic way; they all detect light and convert it to electrical signal and transmits them to the brain to be seen as images.
